Methods for inactivation of seafood Anisakis larvae and prevention of human anisakiasis: a mini-review

anisakiasis is an arising zoonosis induced by parasitic nematodes belonging to the family anisakidae. anisakiasis is often caused by the ingestion of larval nematodes in uncooked or minimally processed seafood dishes, which are regularly consumed by humans. significant potential sources of infection are raw fish (e.g., sushi and sashimi) that can be found in traditional Japanese cuisine and can be part of the culinary tradition of consumption of raw or marinated fish that is particularly diffused in european countries. during the last five decades, the global prevalence of human anisakiasis has been rising, becoming an emergent major public health problem. thus, there is an unmet need for well-defined and cost-effective methods aimed at killing anisakis larvae, thus reducing the incidence of anisakiasis. In this mini-review, we discuss the clinical features of anisakiasis as well as the effectiveness and mechanisms of action of the main methods employed for increasing seafood safety and killing anisakis larvae, including freezing, heating, use of high hydrostatic pressure, salting process, pepsin digestion method and use of garlic oil.
